Illamasqua ESP Lipstick ($26.00 for 0.14 oz.) is described as a “vivid violet.” It’s a rich, violet purple with pink undertones and a matte finish. Nothing that I could think of seemed to come very close–this is very purple; not pink, not fuchsia, and then not ultra dark/vampy. OCC Belladonna was the closest, but it’s lighter. MAC Potent Fig and MAC Fervent are much darker, less violet. MAC Violetta and MAC Heroine are both much pinker. Illamasqua Kontrol is purpler, grayer, and quite a bit darker.
